I have no idea how to make the AI stop doing that. I'll look at the plugin documentation, but the person who authored it is retired.
Hmmm, have you tried looking for a different AI script then? or do you think that editing the current one would be an easier method to try then? (or maybe there's an additional plugin that would work with it?)
honestly, with how it looks like you're trying to make it work, it may need to be more custom made. Though there's a few games that seems to have something similar to what you're trying to do; one's called "Mira Co rescue" and the other is called "Lustfall" Maybe try asking those dev's for some help if they're up to it. Though they do seem busy at the moment, and that's just an idea. It's up to you what to do.
Still, I hope that you have a good day, Christmas, new year, or heck, a good year for the whole of next year, I do really like this demo. Lot's of potential in this game right here.
See ya' at the next update! I'm sure you'll do good no matter what ya do! ^w^
